ATTACHMENT FOR PENCILS AIID PENHOLDEBS.

Specification of Letters Patent.

Patented July 10, 1917.

Application filed. December 12, 1916. Serial No. 136,445.

To all whom it may concern:

Be it known that I, ALFRED C. NEWMAN, a citizen of the United States, and a resident of Fargo, in the county of Cass and State of North Dakota, have invented a new and Improved Attachment for Pencils and Penholders, of which the following is a full, clear, and exact description.

My invention relates to a tubular device adapted to be slipped onto a lead pencil or a penholder and having a strip to be unwound or to be wound thereon. My invention is particularly adapted for embodiment in a variable calendar although not limited in all its phases to such use, since the Strip may be utilized for other purposes as for bearing advertisements or for making memoranda for example.

Objects of the invention are to provide an attachment of the indicated character, adapted to be moved on the pencil or penholder to the front thereof and retained in position for the purpose of protecting the point as well as preventing the point from puncturing the pocket of the user, while at the same time the preponderance of weight thus given to the lower end of the pencil or penholder, and the increased 'diameter given to said lowerend by reason of the attachment, will serve to retain the pencil or penholder in the pocket.

Further objects are to provide efiective friction between the interior of the attachment and the pencil or penholder, and to provide for effectively gripping the inner end of the strip.

Other objects, and the advantages of my improved device, will appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a perspective view of my improved attachment showing the same applied to a lead pencil; v

Fig. 2 is an enlarged, fragmentary, vertical section of the attachment as applied;

Fig. Sis a cross section on the line 3-3, Fig. 2;

Fig. 4 is a plan view of a portion of the strip employed on the spool of my attachment. i

In carrying out the inventlon in practice,

a spool is provided, comprising a sleeve or shell 10 and heads 11, the said spool being made of resilient material, and the bore thereof being sufliciently smaller than the pencil or penholder to which it is to be applied, to require that the spool be somewhat expanded in placing it on the pencil or penholder, whereby to fit friction tight thereon. Preferably, the spool is formed of soft rubber and on the heads 11 there are formed annular resilient flanges 12 oppositely disposed and forming between the inner surfaces thereof and the exterior surface of the sleeve 10, annular recesses 13. The recesses 13 are adapted to receive the side edges of a strip 14: to be used as a calendar or a memorandum strip, or for various other purposes. The arrangement is such that the resilient flanges 12 will overlap and retain the strip 14 as successive convolutions are unwound therefrom.

The strip 14: is formed with transverse score lines 15 and with notches 16 at the ends of the score lines at the opposite edges of the strip, thereby dividing the latter into sections that may be readily torn off. The inner end of the strip is held in a longitudinal slot 17 formed in the sleeve 10 and extending between the heads 11.

The resiliency of the flanges 12 give a gripping action on successive convolutions of the strip and the depth of the notches 16 is such that when the strip is unwound from the sleeve 10 sufficiently to reach a score line 15 and its notches 16 adjacent thereto, the strip will flex or spring outwardly as the flanges 12 overlap the strip short of the notches 16. The attachment may be positioned on the pencil at or near the rear end thereof or may be moved forwardly to protect the pencil point. When projected beyond either end of the pencil, the projecting soft rubber head of the spool will constitute an eraser. In all cases the soft rubber tends to retain the pencil in the pocket by reason of the holding action of the rubber on the pocket material. Also, the preponderance of weight given to the pencil when the attachment is at the pencil point and the pencil inserted point downward in a pocket, will tend to hold the pencil in the pocket. When the strip is used up, the spool may be slipped from the pencil and employed separately as an eraser or either head thereof may be torn off the sleeve 10 V owing .tothethinness of thematerial of the latter and the heads thus separately used as I erasers.

lapsed device then applied to the pencil or pen casing for continued service as a re tainer, point protector and eraser.

In the form illustrated, the invention is embodied in a calendar attachment. For this purpose the initials of the days are produced in horizontal rows and in reverse order on the respective heads 11 In this way it matters not whether the strip 14: is inserted in the recess 13 from left to right or from right to left as in eitherevent the attachment may he slipped ontothe pencil in a manner that one row ofzthe initials ofthe days will be properly disposed at the upper end ofthe=sp0olz Thed'aysof the calendar month'are produced in horizontal and vertical rows so that the vertical rows will aline "with particular days of thexweeln In practicethe interior of thesleeve I0 is initially of gradually increased diameter :toward the center so that the radial distension caused by" inserting the pencil or cas ing will not so distend the central portion of the sleeve as to cause a bulging of the wound strip at the-center. V

The body of the attachment owing to its slidability and readily adjustable qualities and 'also'owing' to: its greater circumference upon the casing-of the lead ipencil or pen- "holder, will supply and provideia superior clutch or gripfor the fingers,. 0r it may be so positionedas may be preferred bytheoperator as for example to aforma moresecu-re thereon to collapse the sleeve 10 and the'colsleeve near the ends to hold the strip on the spool, the said-means including resilient annular flanges oppositely disposed and radially outward from the sleeve to form recesses to receive the opposite edges of the strip, the resiliency .of the flanges yieldingly gripping the strip as successive convolutions are unwound.

12. In anattachment of the class described,

a core, and soft rubber heads thereon at the oppositelends, said heads having annular flanges thereon disposed. toward each other and adapted to hold a strip on the core between the said-heads.

3. .Inanattachment of the class described, the combination of a spool having heads thereon, said heads having resilient flanges disposeditoward each other, the flanges being positioned radially outward from the sleeve and spaced from each other, and a strip wound on said sleeveand overlapped at its opposite edges by the said resilient flanges, the saidstrip having score lines dividing it jinto sections,and notches at opposite edges at the score lines, the overlapping portions of the flanges terminating at the inner ends of the said notches.
